Husqvarna 394xp build/mod

[coolpool]

I love unique builds and this is just plain awesome. That saw doesn't even sound like it wants to slow down in your vids even when your cutting up the length and getting big chips. Very nice!

Thanks man. This has been a fun and rewarding project through and through. The 394 is an impressive machine but it does wear on the operator. It's alot of saw but it's very useful in large hardwood.

About a year ago I did a 359 overhaul. It was a pile and missing several parts when I got it. Now it is mildly modded with just a base gasket delete and basic lower transfer work. Now it is a good running well mannered saw running an 18" bar with 3/8 full chisel. It's not a screaming banshee like my ported 357xp, but it has a wide torque curve and will pull well when dogged in. I find myself grabbing this saw fairly often.

Here is a pic of what it looked like when I received it and a couple pics of what it looks like now.

Like the saw stand

I like this one better

Struggling w a husky 124l weed wacker. A small stand like that would be nice. No spark, plug tester shows spark but I can't get enough to jump the gap on old or new coil. Both adjusted close to the magnets on flywheel. Maybe too close, sigh. I'm about to bend it around a tree.

Should be a .010"-.012 coil/flywheel gap..at least that's the spec on saws anyway

I use a standard business card (not one that is embossed) as a feeler gauge to set the gap on my saws, and it works great. Make sure the magnet on the flywheel and the face of the pickup coil are clean before you set the air gap.

Clean and set can't get old or new coil to fire plug but both fire tester and plug works in other machine. I can't use that coil in second machine as it is a different setup but plug works.
Old coil 1500 ohm and something huge like 1.5Mohm, only reads one way, otherwise OL
New is 370ohm 3500ohm. Seems more normal, gap is about a card. Can't get it closer. So confused, outside of magnets not having enough field or my new coil is also bad....

A friend of mine says he uses a piece of notebook paper to set the air gap. I wouldn't think that would work, but paper is thinner than card stock, so the gap would be closer.

New coil aftermarket or OEM? It's possible to get a bad new coil, especially with aftermarket coils

[plastikosmd]

Aftermarket china

Tell them it's a bad coil?

Have you tried to start it with the kill switch unhooked ?

Yes kill is disconnected
Coil was ordered via Amazon
I will see if I can find another local

[RIDE-RED 250r]

A coil that does not fire when the kill circuit is disconnected from it is indicative of a faulty coil. By default they should fire when the flywheel magnets pass by the armature. It is only by grounding them that ignition is disabled shutting down the engine....

As much as its nice to save money on parts, chinese parts, particularly electrical parts like coils can be very hit and miss. As I mentioned earlier in this thread, I am active on a couple of saw forums. Lots of back and forth on chinese parts and saws there. One very common theme I have read about id chinese coils failing prematurely, causing engine to not perform up to par, or not working at all. An OEM coil should be under $50 and in this case experience of others indicates you are better off with the OEM part. I'll look up your weedwacker and see if I can find a rough cost for your coil... Stand by.

Ok, if you click this link: https://www.partstree.com/parts/husq...-brush-cutter/ You can see 4 or 5 links to your model but different year runs. I clicked the first and found that your coil is 38 bucks (number 40 in the diagram). I'm not sure what year your 124L is, but you should click the link appropriate for your model year to make sure you get the correct part.

Here is the diagram I looked at, again might not be your year. It's the 2006-05 parts listing.. https://www.partstree.com/parts/husq...tank-ignition/

If you don't want to order from here, just jot down the part number to your coil and call your local Husky dealer.
